Description of the Related Art For example, in a disk drive in which a magnetic disk cartridge is mounted, when a disk cartridge is inserted into a holder, a slider slides and the holder moves from an eject position to a mounting position in conjunction with the slider. Has become. The disk housed in the disk cartridge is mounted on the turntable while the holder moves to the mounting position.

[0003] When a disc cartridge mounted on a disc device is pressed by an eject button provided at a front end of a slider, the holder is moved from a mounting position to an eject position, and is simultaneously ejected from the holder.

[0004]

Such a disk drive has a configuration as shown in FIGS. In both figures, 1 is a chassis, 2 is a slider, and 3 is a holder.

A side surface 1a of the chassis 1 is provided with a U-shaped groove 1b for guiding the holder 3 up and down. or,
The slider 2 has a long hole 2a into which a guide pin 1c implanted in the chassis 1 fits, and the long hole 2a slides while the sliding direction is regulated by the guide pin 1c.

[0006] The inclined grooves 2 are formed on both side surfaces 2 b of the slider 2.
c are provided on both sides of the holder 3, and the projecting pins 3 a that fit into the inclined grooves 2 c of the slider 2 and the grooves 1 b of the chassis 1.
Is provided. Therefore, when the slider 2 slides in the direction A, the projecting pin 3a of the holder 3 is pressed in the direction C along the inclined groove 2c, and the holder 3 moves in the direction C.

As described above, in a disk drive in which the holder 3 moves in conjunction with the sliding operation of the slider 2, if the sliding distance of the slider 3 becomes too long, the holder 3
Projecting pin 3a is disengaged from the inclined groove 2c of the slider 2 and becomes inoperable.

For this reason, in the disk device having a structure in which the eject button is manually operated as described above, the front end 2 of the slider 2

To limit the sliding limit position of the slider 2 (the position where the protruding pin 3a does not come off the inclined groove 2c).

In the above configuration, the guide pin 1c and the long hole 2
Since a is fitted, the sliding position of the slider 2 can be regulated by the length of the long hole 2a.

However, when assembling the slider 2 and the holder 3 to the chassis 1, it is necessary to shift the slider 2 in the A and B directions. No.
Therefore, the elongated hole 2a cannot be used as a means for regulating the sliding position of the slider 2.

On the other hand, instead of the above-mentioned configuration, a disk drive having a drive mechanism for sliding a slider by driving a motor is being developed. However, since the motor-driven mechanism does not have the eject button as in the manual type described above, a stopper for regulating the sliding limit position of the slider must be separately provided, which increases the number of parts and the installation space. There arises a problem that extra is required.

Therefore, an object of the present invention is to provide a disk device which solves the above-mentioned problems.

[0013]

SUMMARY OF THE INVENTION The present invention has a slider slidably provided on a chassis and a storage portion into which a disk cartridge is inserted, and ejects a cartridge in conjunction with the sliding operation of the slider.

Therefore, when the slider 13 slides in the direction B by inserting the disk cartridge, the holder 14 moves in the direction D to reach the mounting position, and when the slider 13 is driven in the direction A by the eject operation, the holder 14 moves in the direction C. To the eject position.

Here, the driving mechanism 15 will be described with reference to FIGS. In each figure, the drive mechanism 15 includes the base 16 and a motor 32 attached to the base 16.
And an upper base 33 facing above the base 16, and a drive gear 34 having a drive pin 15 a loosely fitted in the recess 27.
And a plurality of reduction gear groups 35 disposed between the output shaft 32a of the motor 32 and the drive gear 34.

As described above, the base 16 is provided with the stopper 20 erected so as to extend in the directions A and B, and the motor 32.
, A support 16b, 16c for supporting the upper base 33, and a shaft 1 for supporting the reduction gear group 35.
6d and 16e. The drive mechanism 15 is previously assembled as a single assembly, and is fixed to the mounting portion 17 and the support column 18 of the chassis 12 as shown in FIG. When the drive mechanism 15 is attached to the left corner of the chassis 12 as described above, the stopper 20 on the base 16 is disposed at a position facing the contact portion 13a of the slider 13.

Here, the operation of the driving mechanism 15 will be described. As described above, the disk cartridge is
When inserted into the disk cartridge, the rotating arm 28 pressed against the front edge of the disc cartridge rotates clockwise to
The lock of the slider 13 by d is released. Therefore, the slider 13 slides in the direction B by the spring force of the springs 25 and 26, and moves the holder 14 in the direction D. This allows
The disk cartridge reaches the mounting position together with the holder 14 and can perform magnetic recording and reproduction.

At this time, the contact portion 13a of the slider 13
Is separated from the stopper 20 as shown in FIG. Then, the drive pin 15a is
7 is loosely fitted.

When the eject switch (not shown) on the front bezel is pressed after the completion of the magnetic recording / reproduction, the driving mechanism 1
The motor 32 of No. 5 starts. The rotational driving force of the motor 32 is transmitted to a driving gear 34 via a reduction gear group 35. Accordingly, the drive gear 34 rotates clockwise as shown in FIG. 9B, and brings the drive pin 15a into contact with the inner wall 27a of the recess 27.

Therefore, the slider 13 moves in the direction A by being pressed by the driving pin 15a which rotates clockwise.

When the slider 13 reaches the eject position,
The contact portion 13a also contacts the stopper 20 provided on the base 16, and the movement in the direction A is restricted. Therefore, the slide limit position of the slider 13 is regulated by the stopper 20, and the protruding pins 14 g to 14 k of the holder 14 are
Stop at a position that does not deviate from k to 13n.

As a result, after the holder 14 moves in the direction C, the turning arm 28 turns counterclockwise as shown in FIG. 5 to eject the disk cartridge in the holder 14 in the direction B.

The slider 13 is locked at the eject position moved in the direction A by the locking pin 28d of the rotating arm 28. Next, the output shaft 32a of the motor 32 rotates in the reverse direction to move the drive pin 15a away from the inner wall 27a and return it to the approximate center of the recess 27.

Thus, a series of ejection operations by the drive mechanism 15 are completed, and the apparatus stands by in a state where the next disk cartridge can be inserted.

If the drive mechanism 15 breaks down and the mounted disk cartridge cannot be ejected, a metal rod is inserted through a small hole (not shown) of the front bezel facing the pressing portion 13q. Pressing part 13
Press q in direction A. Thereby, the slider 13 can slide in the ejecting direction, and the disc cartridge can be ejected into the holder 14 by manual operation.

In this case, since the concave portion 27 of the slider 13 is sufficiently large, even if the slider 13 is manually moved in the direction A as described above, the concave portion 27 does not come into contact with the drive pin 15a and hinders the operation of the slider 13. Absent.

Although the above embodiment has been described by taking a disk device on which a flexible magnetic disk is mounted as an example, the present invention is not limited to this, and it is needless to say that the present invention can be applied to other types of disk devices. is there.

[0043]

As described above, in the disk drive according to the present invention, the stopper is provided independently on the motor mounting base of the drive mechanism for driving the slider to regulate the sliding limit position at the time of ejection. Since the number of parts is smaller than in the case where it is provided, not only does the assembling work take less time, it is not necessary to provide an extra space for mounting the stopper, so that the limited space in the apparatus can be effectively used and the apparatus can be downsized.
